What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

Well, it is complete for now. My painting skills with too few cans of bed liner are showing but I got the edges sealed so the MDF won't swell if there's any water getting to it. I think I'll have to come back and carpet the top after all to really be happy long term but this will do great for the long weekend trip we have coming up tomorrow.

You can see the pockets I routed out for the two spots that are higher than everything else for no reason.


I am not sure yet what I will do to hide the two corners where the side trim meets the sill plate but that will get filled in eventually.


I actually did make a piece to go in this bare section behind driver side second row it just managed to not make it into the shot. The low frequency antenna lives in the middle and it was easier to cut off a piece from the floor and have a separate filler piece to protect and support.


Finally here's the "completed" shot. I will probably trim the lip of the weathertech mat in the back so that the carpet can lay over it flatter but otherwise I'm ready to drive this thing all over the next few days.

Carpet looks like someone got dragged out.

Yeah, you're not alone in that everyone seems to notice the "bloody" handprint, lol.

Very clean installation. Looks factory. Really nice job.

I knew keeping this thing around for years would pay off one day. Face Skeezer...

I don't have a tahoe but I feel left out‍. So I bought more tahoe parts for my Sierra.
I got some 20" steel wheels off of a 2023 PPV tahoe. To use as the new spare tires for my 14 and 18 after I complete the 4 piston caliper brake upgrades.

i am curious to know if it fits in the spare area I have a 20" 33" tire ( i need to find a 20" wheel) I would like to use as a spare but it looks like it might touch on the tail pipe

I will let you know when I get it mounted up and put under the truck.

I don't know if it helps you but for reference, I have a factory 22" as a spare and it fits fine on my Yukon XL.

Factory 20 or 22 being the same overall height will fit.

Drove it 1500 miles over the weekend and managed to average 16.5mpg despite the wind. Surprisingly, it got great mileage in the mountains (18+) but once we hit the prairie and we were opened up to the wind it demolished the MPG on the way there AND back. Great vehicle so far aside from the abysmally lackadaisical transmission but @BlackBearPerf emailed my new tune on Friday so that should hopefully be resolved now.

If only they had got to me a day earlier I could have vacationed with the new tune but for some reason the GF thought it was "irresponsible" to flash the ECU in the middle of an out-of-state road trip in the middle of nowhere...
